Is anybody familiar with this gun? I'm working my way up to shooting a 2700 all revolver(still need a .22). The gun is NIB. It seems to have a preference for jacketed bullets. It grouped much tighter with Winchester white box 230gr than it did with 200 gr LSWC. I could be premature in that assessment as I just got it.....

The 625 is a really good pistol. I am a little surprised that the 230 gr are doing better then the LSWC's. You may be having a tad bit of follow thru problem and the hotter loads are clearing the barrel faster. I load a 200gr LSWC with 3.8 gr Bullseye and that load will shoot very good groups in my Model 25. You would not need to get a different pistol for CF as you already have the best pistol for shooting accurate lead bullets. My recommendation for a .22 would be a S&W model 17-6. There is one for sale on GB but is a tad spendy. My other choice would be any of the model 17s built pre-lock. The one below is an excellent example. I have no ownership in it.

Ric you are in the sweet spot on those billets. Just don't try to push them to fast. I have found that anything over 775fps you will have leading and accuracy problems. My gun likes 4.2 of BE for the long line and I use 3.9 for the short line.
